What are the cast of MASH doing now?

As of my last knowledge update in October 2023, many of the main cast members of "MAS*H" have passed away, including Alan Alda, who remains active in advocacy and writing, particularly focusing on science communication and aging. Loretta Swit, known for her role as Margaret Houlihan, continues to be involved in animal rights activism and has participated in various charity events. Jamie Farr, who played Max Klinger, has engaged in guest appearances and convention circuits. Other cast members, like Mike Farrell and Harry Morgan, have also been involved in various causes and projects before their deaths.
